5. Drive Gain knob
Gain control for the distorted channel.
With a little value you can obtain
crunch effect or overdrive. By adding
gain, distortion is added until reading
high gain. Note, that for guitars with
Humbucker pick-ups and high output
signal, it is possible, that turning the
knob to the right, does not cause more
distortion, but more noise. It is
designed that way, to allow low signal
guitars also to reach high-gain.
HINT: To find the best volume balance
between clean and drive channel, use
Clean Gain knob; in lower Drive Gain
settings, it's better to work in lower
Clean Gain settings and the other way
around.
6. Bass knob
Adjusts the low-frequency.
7. Treble knob
Adjusts the high-frequency tone for
both channels.
HINT: Set all the potentiometers in a
12.00 o’clock position, then adjust
them individually to get the best
sound. Remember, that the frequencies
of each controller are related to each
other, the change of one influences the
other.
8. Master Volume knob
Master volume control.
HINT: Besides controlling the volume,
it influences saturation of the clean
channel. Therefore, when turned down
to a lower level, a crunch sound can be
obtained on the clean channel.
9. Stand By / Power selector switch
In the middle position (“0”), the
amplifier is in the standby mode.
Switching to any other position, sends
the plate voltage to the tubes – in
these positions the amplifier plays.
To work in 15W mode, switch to “I”.
To work in 8W mode, switch to “II”.
Before turning the amp in, you should
check, if switch is in the “0” position.
Then wait about 1 min. before
switching to either “I”, or “II” mode.
HINT: Both settings makes the circuit
working with different plate voltages –
the 8W mode - with lower voltage.
Therefore if you normally operate at
low volumes, use the 8W mode to
prolong longer life span.
10.Power switch
The switch turns the mains power
supply on and off. The amplifier is off
when the switch is in position “0” –
then the red indicator lamp is not
illuminated.
The amplifier is on when the switch is
in position “I” – the switch is
illuminated in red.
IMPORTANT: Before turning the
amplifier on, always make sure that
the Standby switch is in position “0” –
it will extend the life span of the tubes.
The amplifier should be turned on in
the following way: first, turn on the
Power switch and wait about 1 minute.
Next, you can turn the Standby on.
Turning off the amplifier works the
other way around. First, turn the
Standby on, then wait about 1 minute,
afterward you can turn the Power off.
